Each force has its corresponding quantum field from "summary" of The Quantum Theory of Fields by Steven Weinberg,Weinberg S
In the quantum theory of fields, each of the fundamental forces of nature is associated with a corresponding quantum field. The electromagnetic force, for example, is described by the electromagnetic field, while the weak nuclear force is associated with the weak nuclear field. These fields interact with particles in a way that is governed by the principles of quantum mechanics. Quantum fields are not static entities, but rather dynamic and ever-changing. They can fluctuate and vibrate, giving rise to particles that can appear and disappear in a seemingly random fashion. This dynamic nature of quantum fields is a fundamental aspect of the quantum world, where particles are viewed not as discrete objects but as excitations of underlying fields. The interactions between particles mediated by these quantum fields are responsible for the forces that govern the behavior of matter at the most fundamental level. For example, the electromagnetic field is responsible for the interactions between charged particles, while the weak nuclear field is involved in processes such as beta decay. By treating particles as excitations of quantum fields, the quantum theory of fields provides a unified framework for understanding the behavior of matter and the forces that act upon it. This approach allows for a consistent description of the interactions between particles and forces, leading to a deeper understanding of the underlying principles of the universe. In this way, the concept of each force having its corresponding quantum field lies at the heart of the quantum theory of fields, providing a powerful and elegant framework for describing the fundamental forces of nature and the particles that interact through them. Through the study of quantum fields, physicists have been able to make significant progress in understanding the fundamental nature of the universe and the forces that govern it.
